Related Art
The description in this section merely provides background information related to the present disclosure and does not necessarily constitute the prior art.
Riverbed scour is a main cause of a bridge disaster by flood. When a river passes through a substructure of a bridge, the river scours the riverbed, especially the riverbed near bridge piers. The prolonged scouring causes the riverbed to sink, and the bridge piers and abutments are gradually exposed to the water environment. The bearing capacity of the bridge piers and abutments that lose the surrounding riverbed support decreases seriously, causing collapses.
The inventor finds that the existing riverbed monitoring methods have disadvantages such as inaccurate positioning, harsh working environment requirements, and lack of universality.
To resolve the foregoing problems, in a first aspect of the present disclosure, a magnetic tag sensor is provided. The magnetic tag sensor highly simulates a magnetic dipole module in form and height, and the generated magnetic field is more stable, which is convenient for later analysis.
To achieve the foregoing objective, the present disclosure uses the following technical solutions:
